; ===== How can I check package signatures? =====See [[Package signatures]] ===== Is it possible to run x86 VPS on a x86_64 arch?=====: Sure :) We actually did some work on that to enable migration of x86 VE from x86 to x86_64 and back, and to enable using 32-bit iptables in 32bit VE on an x86_64 system.

; ===== How do I set up VPN for a VE? =====See [[VPN via the TUN/TAP device]] ===== What is veth and how do I use it?=====: See [[Virtual Ethernet device]]

; ===== How can I reset <code>failcnt</code> in <code>/proc/user_beancounters</code>?=====: In short — only by stopping and starting a VE. In some cases you need to keep VE in a stopped state for a few minutes.

: Long answer: there can be many application who reads /proc/user_beancounters, and thus if you will reset it you gonna have problems with those other apps.: Consider what happens if you will reset you sent/received packets/bytes statistics on the network interface — programs which reads will be screwed up.: So the proper thing to watch for is not the current value of, say, failcnt, but whether it is increased (from the previous reading) or not. You can write a simple shell script to do just that.
